I am reaching out hoping someone can enlighten me with two questions. Thank you all in advance!
I am currently working at simulating the complete sewer system of a municipality. The system is roughly composed of 100 km of pipes, 13 lifting pumpRead more…
I am using daily rainfall data to model my catchment. For the time series, does rainfall have to be 7 digits. for instance, 0mm of rain inserted as 0000000 and 2,2mm as 000002,2. my supervisor has told me to use this way of inserting data. wRead more…
Very new SWMM user here. Interested in defining some LID Controls so I can select them for my subcatchments in the drop down menu in the editor.
It seems I need to first define the Controls and how they are routed using the specialized proRead more…

I am currently attempting to model in SWMM Stormtech chambers as a subsurface pond/storage unit connected to a surface pond with a higher stage. How do I cap off the underground system so water will not pond higher than the top of my chambers? When iRead more…
Very glad that i join the group.
am new to SWMM5.1.12 Version.currently am doing modeling the stormwater for a small urban catchment.no difficulties while studying and applying the model but i only have daily recorded rainfall data-set which am confu
In this blog we example the St Venant terms used in SWMM5 as equations, table, graphs and units. We use a QA/QC version of SWMM 5 that lists many more link, node, system and Subcatchment variables than the default SWMM 5 GUI and engine.
Hi everyone! I'm currently new to SWMM (real beginner) and I would just like to ask for some help from you.
I'm trying to model LID facilities using SWMM. I wanted to compare our observed data from our manual monitoring and the simulation data from S
A methodology for linking 2D overland flow models with the sewer network model SWMM 5.1 based on dynamic link libraries
Have you ever thought about enhancing your 2D model to be able to cope with complex sewer networks? We have published an article explaining you how you could do it based on DLLs and we provide the code for the 3 new functions you need to add to SWMMRead more…
I have to add time series of tidal water level as downstream boundary condition. The dataset contains one high water level and one low water level for each day. How can I introduce this dataset as boundary condition?Read more…
I'd like SWMM to calculate Evaporation. I've to prepared a user prepared text file with the information listed in the manual (section "climate files"). The text file, spaced delimited, looks like:

As the topic of this post states, it is a way to add Twitter and Facebook comments in one stream. It unlike Facebook and Twitter allows some editing of the stream. Hydrology and Hydraulics Twitter/Facebook Like FeedRead more…
I want to have separate rating curves for filling and emptying of a storage tank. Is this possible in SWMM? If yes, could anybody tell me how?Read more…
I'm wondering about the validity of the flow velocity calculation for user-supplied conduit shape curve.
I simply compared the discharge/velocity/depth calculated with a rectangular closed shape and exactly the same curve but defined asRead more…
